Question

I’m accessing the address book and have this line and am compiling using ARC:

 ABMultiValueRef phoneNums = ABRecordCopyValue(person, kABPersonPhoneProperty);

Does this line need to be rewritten as:

ABMultiValueRef phoneNums = (__bridge_transfer ) ABRecordCopyValue(person, kABPersonPhoneProperty);

If yes then shouldn’t the compiler have generated a warning?
If not then maybe I don’t understand using ARC in conjunction with core framework thoroughly.

Answer 1

No, you should not bridge in this case. ABMultiValueRef is a CFTypeRef. ABRecordCopyValue returns a CFTypeRef. There is no bridge required.

Bridge casting is required when you convert between id and CFTypeRef (which is a synonym for void*).
